“…In the past few decades (see Refs (148,8)), several turbulence models have been developed for flows of general interest and for aerodynamic flows. Dynamic stall occurring on helicopter blades and wings always involves high Reynolds number turbulent flow.…”

“…The software complex IPMFlow implements the following elements of the mathematical model: the Reynoldsaveraged nonstationary Navier-Stokes equations [26][27][28][29], several differential turbulence models, including an SST two-parameter model of turbulence of Menter [30][31][32][33] and implicit quasi-monotone high-order ENO-scheme [34][35][36]. To account for thermodynamic properties of the working medium, an analytical interpolation method is used for approximating equations of the formulation IAPWS-95 [37,38].…”

The paper describes an algorithm for the design of axial and radial-axial type turbines. The algorithm is based on using mathematical models of various levels of complexity -from 1D to 3D. Flow path geometry is described by means of analytical methods of profiling using a limited number of parameters. 3D turbulent flow model is realised in the program complex IPMFlow, developed based on the earlier codes FlowER and FlowER-U. Examples of developed or modernized turbines for differentpurpose power machines are presented. They are: an expansion turbine, ORC turbine and cogeneration mediumpressure turbine.

“…We will give here a demonstration based on the inverse differential filter [23] coupled to the integral filter (10) The interest for such researches was at that time very scarce. We quote from Monin and Yaglom [7], volume This attitude radically changed with the advent of the computer.…”

“…In order to overcome these difficulties methods have been proposed that should produce directly the statistical quantities. They are based on the Reynolds Averaged N a vier Stokes equations, RANS, and rely on models that are currently applied to complex geometries such as airplanes, but that till now are not so universal as we would like [7,8,9,10].…”

From the numerical point of view the Large Eddy Simulation can be interpreted as a procedure to solve under resolved Navier-Stokes equations. As such the methods applied to model the scales smaller than the scale resolved on the computational mesh can be read as one of the many ways to increase the numerical resolution.From the theoretical point of view a Large Eddy Simulation can be formalized as a filtered solution of the Navier-Stokes equations. Filtering can be done in different ways : truncations in the spectral space, convolutional integrations in the physical space and in general we can formalize all that operationally as due to some averaging operator provided with some particular properties. Obviously the theoretical difficulties are due to the fact that it is relatively easy to filter data but usually very hard to filter equations.In these lectures the fundamentals of the Large Eddy Simulation will be examined and discussed in order to provide and as possible to justify the main ingredients of such approach, the subgrid scale models. The practical objectives of the Large Eddy Simulations and how they are located between the Direct Numerical Simulations and the Reynolds Averaged Navier Stokes solutions will be exposed. Particular emphasis will be given to the operational approach and to its principal product, the dynamic modelling procedure. et al. (eds.), Advanced Turbulent Flow Computations
